Abstract

A display device that includes a display panel and a container member that accommodates the display panel, where the container member can effectively absorb an external impact to sufficiently protect the display panel from damage and minimize deformation caused by an external stress, a method of manufacturing the same. The container member includes a metal frame including a space that accommodates the display panel, a plurality of sides and a bottom having a first opening; and a mold frame arranged between the sides of the metal frame and sides of the display panel. The display device may also include a buffer tape within the first opening. The mold frame is preferably produced by an injection molding technique.

Claims

1. A display device, comprising:

a display panel; and

a container member, the container member including;

a metal frame including a space that accommodates the display panel, a plurality of sides and a bottom having a first opening;

a mold frame arranged between the sides of the metal frame and sides of the display panel; and

a buffer tape arranged within the first opening of the metal frame, the buffer tape having a thickness equal to a thickness of the bottom of the metal frame.

2. The display device of claim 1, each of the sides of the metal frame includes at least one fastening aperture, the mold frame includes a plurality of sides, each of the sides of the mold frame includes at least one first protrusion arranged at a location that corresponds to the fastening aperture.

3. The display device of claim 1, each of the sides of the metal frame includes at least one step, the mold frame includes a plurality of sides, each of the sides of the mold frame includes at least one second protrusion arranged at a location that corresponds to the step.

4. The display device of claim 1, further comprising a double-sided tape arranged between the display panel and the bottom of the metal frame and between the display panel and the buffer tape to attach the buffer tape to the display panel.

5. The display device of claim 1, wherein the metal frame further includes a plurality of rounded corners, wherein each of the corners have a curvature.

6. The display device of claim 1, wherein each of the sides of the metal frame have a hemmed structure.

7. The display device of claim 6, wherein the mold frame is absent of a bottom and is produced by an injection molding process where the metal frame is used as part of the mold.

8. The display device of claim 1, the buffer tape being arranged only within the first opening, and the buffer tape covering an area of the display panel substantially equal to an entirety of the first opening.

9. The display device of claim 1, the mold frame having a bottom that is perforated by a second opening that corresponds to the first opening in the metal frame, the first and second openings being arranged on a side of the display panel where no image is produced or viewed and being opposite to a side of the display panel that displays and image.

10. A method of manufacturing a container member that accommodates a display panel, the method comprising:

providing a metal frame having a bottom and a plurality of sides, the bottom having a first opening, at least one fastening aperture in each of the sides and at least one step in each of the sides; and

forming a mold frame on inner sides of the metal frame by injection molding, wherein the metal frame serves as the mold during the injection molding process.

11. The method according to claim 10, the mold frame comprising

at least one protrusion on each side of the mold frame at a location that corresponds to the fastening aperture that is formed during said injection molding.

12. The method according to claim 11, the mold frame further comprising

at least one protrusion on each side of the mold frame at a location that corresponds to the step.

13. The method according to claim 10, further comprising rounding corners of the metal frame prior to said formation of the mold frame.

14. The method according to claim 10, further comprising producing a hemmed structure by folding the sides of the metal frame prior to said formation of the mold frame.

15. A display device, comprising:

a display panel to display an image;

a metal frame including a space that accommodates the display panel, a plurality of sides and a bottom having a first opening;

a mold frame arranged between the sides of the metal frame and sides of the display panel, the mold frame having a plurality of sides and a bottom having a second opening; and

a buffer tape arranged within the first opening of the metal frame, wherein a size and location of each of the first and second openings correspond to a display region of the display panel and to a size and location of the buffer tape.

16. The display device of claim 15, wherein the metal frame includes at least one fastening aperture arranged in each of the sides, and the mold frame includes at least one first protrusion arranged on each side thereof to correspond to the fastening aperture.

17. The display device of claim 16, wherein the metal frame includes at least one step arranged in each of the sides, and the mold frame includes at least one second protrusion arranged on each side thereof to correspond to the step.

18. The display device of claim 15, wherein the sides of the metal frame have a hemmed structure.

19. The display device of claim 15, further comprising a double-sided tape arranged between the display panel and the bottom of the metal frame and between the display panel and the buffer tape, the double-sided tape to attach the buffer tape to the display panel.

20. The display device of claim 15, the display panel having a first side that includes a polarizer and displays the image, and a second side opposite to the first side that does not display any image, the first and second openings and the buffer tape being arranged on the second side of the display panel.

21. The display device of claim 15, the buffer tape being exposed to an outside of the display device.
